Arc Vuam Qws
Lub vuam qwj yog ib qho khoom siv hluav taws xob uas siv rau cov hlua hluav taws xob uas siv cov hlua hluav taws xob. Nws muaj ob feem: qhov txheej thiab qhov tseem ceeb. Cov txheej txheem hlau uas them los ntawm cov txheej txheem yog hu ua tus cag hlau txuas. Cov tub ntxhais feem ntau yog ib cov hlau hlau nrog ib qhov ntev thiab lub cheeb. Cov tub ntxhais hlua muaj ob txoj haujlwm. Ua ntej, txoj kev siv txoj hlua txuas tam sim no ua rau cov hluav taws xob hlawv ua hluav taws xob ua hluav taws xob. Ob. Lub vuam choj nws tus kheej ua kom tiav raws li ib lub cav hlau thiab melts lub hauv paus hlau ua lub voj. Thaum cov electrode welded, cov tub ntxhais hlau yuav siv ib feem ntawm tag nrho cov hlau txhuam. Yog li ntawd, cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov tub ntxhais kawm ncaj qha cuam tshuam rau qhov zoo ntawm lub weld. Yog li ntawd, cov hlau hlau siv los ua lub vuam ntub ntawm vuam qws cais qhia nws cov hom thiab qhov muaj pes tsawg leeg. Yog tias txoj hlua uas siv rau kev siv fais fab hauv hlau xws li cov chaw nruab ntug, siv cov hlua hluav taws xob, kev siv roj ntom rau cov hlua thiab cov vuam siv roj, nws hu ua cov hlua hlau. Qhov electrode txheej yog hais txog txheej txheej txheej uas siv rau ntawm cov vuam qhov txuas. Daim tawv nqaij yog muab ziab thiab yaj hauv cov txheej txheem welding rau roj thiab cuav. Nws plays lub luag hauj lwm ntawm kev tiv thaiv neeg kho tshuab, kho cov khoom siv hlau kho thiab kev txhim kho cov txheej txheem kev ua. Cov dej txhuam txheej: cov ntxhia (xws li marble, fluorite, lwm yam), hlau alloy thiab hlau hmoov (xws li ferromanganese, ferro titanium, etc.), organic compounds (xws li hmoov nplej, hmoov txhuv nplej siab, thiab lwm yam), tshuaj khoom (xws li titanium dioxide, dej iav, thiab lwm yam). Lub tshuab hluav taws xob txheej txheem electrode yog ib qho tseem ceeb ntawm kev txheeb xyuas qhov zoo ntawm cov hlua.
